Tuna are highly migratory, swimming through international waters belonging to many nations. To manage tuna stocks, countries sharing these resources joined together to create Regional Fisheries Management Organizations (RFMOs). Member nations of these governing bodies are responsible for setting catch limits, monitoring the health of stocks, and regulating the right to fish.

CCSBT – Commission for the Conservation of Southern Bluefin Tuna

Overview
Beginning in the 1980s, several nations (Australia, Japan and New Zealand) began to apply strict quotas to their fishing fleets to address the need to conserve and manage bluefin tuna stocks in the Southern Pacific. In 1994, this voluntary group was formalized, creating the CCBST. Since its inception, the Republic of Korea, Indonesia, the Fishing Entity of Taiwan, Philippines, South Africa and the EU joined CCBST as members or cooperating non-members.

The CCSBT is responsible for setting fishing quotas for the Southern Pacific’s bluefin tuna stock, both in terms of total allowable catch and its allocation among the member states. In this role, the CCSBT is responsible for:

Being the coordination mechanism for member activities in the southern bluefin tuna fishery

Considering and administering regulatory measures

Conducting and coordinating a scientific research program to provide information in support of Commission objectives

Supporting and implementing fishery management

Fostering conservation activities for ecologically related species

Providing a forum for dialogue and discussion

Liaising with other RFMOs in areas of mutual interest

IATTC – Inter-American Tropical Tuna Commission

Overview
The Inter-American Tropical Tuna Commission (IATTC) is the oldest of the Regional Fisheries Management Organizations (RFMOs), created in 1949 by a convention between the United States and Costa Rica. In 1966, the IATTC initiated the world’s first tuna fishery management program, which limited the annual catch of yellowfin tuna.

Responsibilities & Activities
The IATTC collects catch data on fish sizes, quantities and location of catch, as well as biological information on age, growth and reproduction. The IATTC’s staff uses this data to formulate models that estimate the impacts of fishing on the stock. As needed, the IATTC director formulates conservation recommendations to present to members for consideration. Members can accept the recommendations in full or with modifications, or reject them. Unanimous consent is required for approval.
Implementation is the responsibility of each member government; The IATTC is responsible for monitoring compliance.

ICCAT – International Commission for the Conservation of Atlantic Tunas

Overview
The International Commission for the Conservation of Atlantic Tunas (ICCAT), established in 1966, is open to any government that is a member of the United Nations or any specialized agency of the United Nations. Each member government can be represented by up to three commissioners.

Responsibilities & Activities
The Commission is responsible for making scientifically based recommendations designed to maintain the populations of tunas and tuna-like species at levels of abundance that will permit maximum sustainable yields.
Each year, ICCAT meets to receive scientific advice from its Standing Committee on Research and Statistics (SCRS), which it uses to formulate management recommendations. SCRS first presents a report of stock status along with options for achieving certain goals. The appropriate panel may then make a recommendation to ICCAT for consideration. ICCAT can accept, reject or modify the recommendation. Management decisions are binding on the members, unless they object.

IOTC – Indian Ocean Tuna Commission

Overview
The Indian Ocean Tuna Commission (IOTC) was developed in 1993 and entered into force in 1996. The Secretariat was established in Seychelles in 1998. IOTC includes 29 member states and three cooperating states.
Unlike other tuna RFMOs, the IOTC was created within the framework of the UN Food and Agricultural Organization’s (FAO) Constitution. However, the Commission is fully autonomous, both functionally and financially, with the budget supported entirely by member contributions.

Ongoing review of conditions and trends of the stocks of tuna and tuna-like fish

Encouraging, recommending, and coordinating research and development activities

Adopting conservation and management measures to ensure conservation of the stocks

Reviewing the economic and social aspects of fisheries, bearing in mind the interests of developing coastal states

Members elect an executive secretary, who is responsible for the operation of the Secretariat. The Secretariat acts as technical facilitator of the IOTC process. Most scientific work is conducted by national scientists and reviewed by the IOTC Science Committee, which formulates advice and proposes conservation and management measures. The full commission must agree by at least a two-thirds majority.

WCPFC – Western and Central Pacific Fisheries Commission

Overview
In 1979, the Forum Fisheries Agency (FFA) was established to collectively negotiate and harmonize Pacific island states’ control over tuna species within the 200-mile Exclusive Economic Zones created by the United Nation’s Convention of the Law of the Sea.
From the FFA, the Western and Central Pacific Fisheries Commission (WCPFC) was established in 2004 to conserve and manage highly migratory fish stocks in the western and central Pacific Ocean.
Related Links

Responsibilities & Activities
The WCPFC has clear legal authority to deal with all aspects of conservation and management of fish stocks in the western and central Pacific Ocean. The WCPFC conducts scientific studies through its Scientific Committee (SC) and a Technical and Compliance Committee (TCC). Scientists of the Secretariat of the Pacific Community’s Oceanic Fisheries Program (OFP) are responsible for leading much of the scientific research utilized by the committees. The Scientific Committee is also required to work closely with the IATTC, particularly in areas of overlap, as well as with the International Scientific Committee (ISC).
Because of differences over how tunas should be managed in the northern portion of WCPFC’s jurisdiction, a Northern Committee was established to deal with management and conservation issues north of the 20° N.
